The Mars Curiosity Rover has been busy snapping photos (selfies too) of Mars and found something... strange. A small, shiny, metal-looking "protuberance" sticking out from the red planet. Is it some secret lever to open up a world where Martians exist? Or some random space junk? We don't know.

You can see it in the picture above and see it zoomed in on the bottom right hand corner. If you look carefully, you can even see the protuberance's shadow. Whatever it is, it looks a lot different from the red rock that it sits on. What in the hell?

People have suggested wild theories for the metal looking object but it's probably just some part of the rock that is less susceptible to erosion (compared to the rest of the surface). Or maybe it's a weird lighting trick that Curiosity is playing on us. Or a grave for a dying robot? Or who knows. The object, which is only half a centimeter tall, was found by the Curiosity Rover on January 30th, 2013. We might never know what it is. [NASA via Universe Today]
